Effect of organic fertigation on yield and quality of bell pepper (Capsicum annuum var. Grossum Sendt.)

Abstract

Investigation on effect of organic fertigation on growth and yield of bell pepper ( Capsicum annuum var. grossum Sendt.) was carried out at vegetable unit, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu, during 2016-2017. There were nine treatment combinations including organic manures viz ., farm yard manure, vermicompost, bio-stimulants (Humic acid and Sea weed extract) and organic fertigation with Neem cake (two levels viz ., 1:20 and 1:40 dilution). Among the nine treatments, the treatment T 7 (Humic acid granules @ 5g plant -1 + fertigation with Neem cake 1:20) exhibited the highest yield of 580.18 g plant -1 , and it was followed T 1 (RDF 250 :150:150 kg NPK ha -1 ) with 561.5 g plant -1 . However, the lowest yield was recorded under T 8 (FYM @125 g plant -1 + fertigation with Neem cake 1:40) with 319.6 g plant -1 . Among the nine treatments, the per se effect of organic basal supplements derived from the treatment combinations revealed the superiority of humic acid over other organic supplements.
